Moisture displacement system for a visor

Abstract

A visor (26) for a helmet (22) comprises: an air delivery element (34) for delivering air to a surface of the visor (26). The air delivery element (34) comprises: at least one inlet (28) for receiving air from an air source (30); and a plurality of outlets (44) through which air is transportable to the surface of the visor (26). The visor (26) may also include a ridge (84) formed adjacent to the plurality of outlets (44) for creating a Coanda effect in air passing through the plurality of outlets (44).

The invention claimed is: 
     
       1. A moisture displacement system for a helmet visor, the moisture displacement system comprising:
 a helmet which includes a helmet body; 
 a visor which includes an air delivery element for delivering air to an outer surface of the visor, a connector for connecting the visor to the helmet, and a channel formed in the connector for transporting air from an external air source via the connector to the air delivery element; wherein the connector is such that, when the visor is connected to the helmet, the visor is movable between a first configuration in which the transport of air via the connector to the air delivery element is permitted, and a second configuration in which the transport of air via the connector to the air delivery element is restricted; 
 an air source which includes an air pump; and 
 a conduit for transporting air between the air source and the helmet. 
 
     
     
       2. A moisture displacement system for a helmet visor according to  claim 1 , wherein the connector is a pivotable connector for pivotally connecting the visor to a helmet. 
     
     
       3. A moisture displacement system for a helmet visor according to  claim 1 , wherein the air delivery element is a manifold and comprises:
 at a first end, a first inlet for receiving air from an air source; 
 at a second end, a second inlet for receiving air from the air source; and 
 a plurality of outlets through which air is transportable to the surface of the visor. 
 
     
     
       4. A moisture displacement system for a helmet visor according to  claim 1 , wherein the helmet body comprises a padded portion and an outer shell, and wherein the helmet comprises a helmet conduit for delivering air to the air delivery element, the helmet conduit being mounted within the shell. 
     
     
       5. A moisture displacement system for a helmet visor according to  claim 4 , wherein the helmet conduit is at least partially embedded within the padded portion of the helmet body. 
     
     
       6. A moisture displacement system for a helmet visor according to  claim 4 , wherein the helmet conduit is formed integrally with the helmet body. 
     
     
       7. A moisture displacement system for a helmet visor according to  claim 1 , wherein the helmet conduit comprises an inlet for receiving air from an air source, and at least one outlet for delivering air to the air delivery element. 
     
     
       8. A moisture displacement system for a helmet visor according to  claim 7 , wherein the helmet conduit comprises a first outlet for delivering air a first end of the air delivery element, and a second outlet for delivering air a second end of the air delivery element. 
     
     
       9. A moisture displacement system for a helmet visor according to  claim 1 , wherein the conduit is detachably connectable to the helmet. 
     
     
       10. A moisture displacement system for a helmet visor according to  claim 1 , wherein the air source is mountable to a vehicle. 
     
     
       11. A moisture displacement system for a helmet visor according to  claim 1 , wherein the air source is configured to receive power from the vehicle, and is controllable using a controller formed integrally with, or mounted on, the vehicle. 
     
     
       12. A moisture displacement system for a helmet visor according to  claim 1 , wherein the air delivery element comprises a plurality of outlets which are oriented such that air is able to flow out of the outlet in a direction substantially parallel to an adjacent surface of the visor.
